What is a absolute value of 1-31

Answers

1-31= -30.
Taking an absolute value makes any value positive, so -30 becomes 30.

The absolute value of 1-31 is 30.

abs (1-31)
= abs(-30)
= 30.

Absolute value of any number is always >=0.

Final answer: abs(1-31)= 30.

Answers

7.5 x 30, 5/2 x 3 is 7.5, and 5/2 times 12 is 30

Answer:

the awnser is A 7.5 ft by 30ft

Step-by-step explanation:

5/2 of 3 is 7.5 since 5/2 as a decimal is 2.5 so do 2.5 x 3

then 5/2 of 12 would be 30 since again 5/2 as a decimal would be 2.5 so 2.5 x 12

A trampoline gas an area of 49 • pi square feet. What is the diameter if the trampoline?

Answers

So,
if the area is 49pi, and the formula for the area of a circle is radius squared times pi,

The square root of 49 is 7.
The radius is 7.
To find the diameter, you multiply the radius by 2 because the radius is half of the diameter.
7x2=14
The diameter is 14 square feet.
Hope I helped!

$area (S)= \pi r^2$
so
$49 \pi= \pi r^2$
so r^2=49 then r=7
diameter is 2*r=2*7=14
